Cadillac: 1968-1976, 472-500, non-EGR, dual plane, spread bore flange, aluminum, Performer intake manifold
This Edelbrock Performer is designed for 1968-76 Cadillac 472 and 500 cubic inch engines. For either square- or spread-bore carbs, it's the first intake designed specifically for high-performance Cadillac's using standard heads. Like all Edelbrock Performers, this manifold increases torque and horsepower from idle to 5,500 rpm. The broad powerband is ideal for high-performance street and engine swap applications. Specs on this non-EGR manifold include a carb pad height that's 3 in. taller than stock. Dropped divider wall evens air/fuel ratio throughout the rpm range.
